💰 Swap Wallet

The Wallet is your personal digital vault where you store, manage, and transact with all your tokens. It's the central hub for all your DeFi activities on the platform.

Overview: Your Digital Wallet

What is the Wallet: The Wallet is your personal digital vault where you store, manage, and transact with all your tokens. It's the central hub for all your DeFi activities on the platform. Think of it as your bank account, but completely decentralized and under your full control.

Accessing the Wallet:

  1. Connect your wallet using the "Connect" button in the top-right corner

  2. Once connected, click on your address to open the full wallet interface

  3. The wallet opens as a dedicated page with complete functionality

Core Philosophy: In real DeFi, your wallet is your identity. Understanding wallet management is crucial because:

  • Non-custodial: You control your assets, not a third party

  • Self-sovereign: No one can freeze or seize your funds

  • Transparent: All transactions are on-chain and verifiable

  • Irreversible: Mistakes can't be undone (in production)


Wallet Personalization

The platform allows complete customization of your wallet to make it truly yours.

Custom Wallet Name

What it is: Give your wallet a memorable, personalized name instead of just showing the address.

How to customize:

  1. Click directly on the wallet title (defaults to "My Wallet")

  2. The title becomes editable

  3. Type your desired name (e.g., "Trading Wallet", "Main Portfolio", "DeFi Experiments")

  4. Press Enter or click outside to save

Use cases:

  • Multiple wallets: Differentiate between different accounts

  • Purpose-specific: Name by function (Trading, Savings, Airdrops)

  • Personal branding: Make it uniquely yours

  • Organization: Keep track of what each wallet is for

Real-world application: While blockchain addresses are immutable, wallet software (MetaMask, Ledger, etc.) allows naming accounts locally. This is crucial when managing multiple wallets for different purposes.

Color Customization

What it is: Choose from 7 color schemes to personalize your wallet's appearance.

How to customize:

  1. Click the Settings button (⚙️) in the wallet header

  2. A settings panel expands below

  3. Under "Wallet Color", see a palette of 7 colors

  4. Click any color circle to select it

  5. The change applies immediately across:

    • Wallet avatar circle

    • Wallet title color

    • Total balance section background and border

    • Various accent elements

Available colors:

  • Blue (#3B82F6): Professional, trustworthy (default)

  • Green (#10B981): Growth, profit-focused

  • Purple (#8B5CF6): Creative, unique

  • Orange (#F59E0B): Energetic, active trading

  • Red (#EF4444): High-risk, aggressive

  • Pink (#EC4899): Personal, distinctive

  • Cyan (#06B6D4): Cool, analytical

Visual feedback:

  • Selected color shows white border

  • Slight scale animation on selection

  • Instant preview across the entire wallet

Balance Privacy Toggle

What it is: Hide or show your token balances for privacy in public settings.

How to use:

  1. Click the eye icon (👁️) in the wallet header

  2. Toggle between:

    • Visible: Shows all amounts and values

    • Hidden: Replaces all numbers with "••••••"

What gets hidden:

  • Total balance amount

  • Individual token balances

  • USD values

  • All numeric displays

When to use:

  • Screen sharing: During video calls or presentations

  • Public places: When using devices in coffee shops, airports

  • Screenshots: Before taking or sharing screenshots

  • Privacy: When you don't want observers to see your holdings

Real-world importance: In production DeFi:

  • Your wallet balance is publicly visible on blockchain explorers

  • Anyone with your address can see all your transactions

  • Privacy practices are essential for security (preventing targeted attacks)

  • Consider using multiple wallets for different purposes


Total Balance Overview

What it displays: The prominent balance section shows your complete portfolio value at a glance.

Components:

Total Balance (USD):

  • Displays aggregate value of all tokens in your wallet

  • Calculated by: (Token Amount × Token Price) for each holding

  • Updates in real-time as prices change

  • Format: $X,XXX.XX with thousands separators

24h Change:

  • Shows profit/loss in last 24 hours

  • Format: +$XXX.XX (2.XX%) or -$XXX.XX (-2.XX%)

  • Green color with ↑ icon for gains

  • Red color with ↓ icon for losses

  • Simulated based on token price movements

Visual design:

  • Large, prominent display for quick reading

  • Colored background matching your wallet theme

  • Subtle transparency and border effects

  • Gradient styling for premium feel

Calculation details:

For each token you hold:
Token Value = Balance × Current Price

Total Balance = Sum of all Token Values

24h Change = (Current Total - Total 24h Ago) / Total 24h Ago × 100

Example:

Holdings:
- 10 ETH @ $2,847 = $28,470
- 5,000 USDT @ $1.00 = $5,000
- 50 BNB @ $312.45 = $15,622.50

Total Balance: $49,092.50

The wallet has two main views accessible via tabs.

Swap Functionality

What is a swap: A swap is the exchange of one cryptocurrency for another directly through a decentralized exchange (DEX). This is the core functionality of platforms like Uniswap.

Understanding Token Swapping

The mechanics:

  • Automated Market Maker (AMM): Algorithmic pricing based on pool ratios

  • Liquidity pools: Reserves of token pairs that enable instant trading

  • Price impact: Your trade affects the token price based on size

  • Slippage: Difference between expected and executed price

Why swap:

  • Convert between cryptocurrencies

  • Take profits (crypto → stablecoin)

  • Enter positions (stablecoin → crypto)

  • Rebalance portfolio

  • Access tokens not on centralized exchanges

How to Perform a Swap

Step-by-step guide:

1. Open Swap Interface

  • Click purple "Swap" quick action

  • Or select swap from available tabs

2. Configure Source Token (FROM)

Select the token you want to exchange:

  • Dropdown shows all tokens you have balance in

  • Only tokens with available balance are selectable

  • Example: ETH, USDT, BNB

Enter the amount to swap:

  • Input field for quantity

  • Shows available balance below

  • Format: "Balance: X.XXXX TOKEN"

  • Cannot exceed available balance

Balance validation:

  • Real-time check of sufficient funds

  • Error if amount exceeds balance

  • Visual feedback on input

3. Use Token Inverter (Optional)

The circular button with bidirectional arrows (🔄):

  • Swaps the FROM and TO tokens instantly

  • Useful for reverse operations

  • Maintains entered amount

  • Quick workflow enhancement

4. Configure Destination Token (TO)

Select the token you want to receive:

  • Dropdown shows all available tokens

  • Independent of current holdings

  • Example: USDT, BTC, MATIC

View estimated output:

  • Automatically calculated based on:

    • Current token prices

    • Exchange rate

    • Amount entered in FROM field

  • Formula: (FROM amount × FROM price) / TO price

  • Updates in real-time as you type

Display format:

You will receive: ~X.XXXX TOKEN

The ~ (tilde) indicates "approximately"

5. Review Exchange Details

Before proceeding, verify:

  • Exchange rate: Conversion ratio between tokens

  • FROM amount: Exact quantity being swapped

  • TO amount: Expected receipt (estimated)

  • Available balance: Ensure sufficient funds

Example calculation:

Swap: 10 ETH → USDT
ETH price: $2,847
USDT price: $1.00

Calculation:
10 ETH × $2,847 = $28,470
$28,470 ÷ $1.00 = 28,470 USDT

You pay: 10 ETH
You receive: ~28,470 USDT

6. Execute Swap Click "Swap Tokens" button (gradient purple-pink)

Swap Best Practices

Before swapping:

  1. Check current prices: Ensure rates are favorable

  2. Verify amounts: Double-check quantities

  3. Review modal: Read all details in confirmation

  4. Consider timing: Market conditions matter (in real DeFi)

During swap:

  1. Read confirmation carefully: Last chance to cancel

  2. Verify TO token: Ensure it's correct

  3. Check estimated amount: Seems reasonable?

After swap:

  1. Confirm balance update: Both FROM and TO

  2. Check Activity tab: Transaction recorded

  3. Review outcome: Did you receive expected amount?

Real-World Swap Considerations

In production DeFi:

Gas fees:

  • Every swap costs ETH (or native token)

  • Fees vary: $1-$100+ depending on network

  • Higher gas = faster confirmation

  • Can exceed swap value for small amounts

Price impact:

  • Large trades significantly move price

  • More impactful in smaller pools

  • Can lose 5-10%+ on big swaps

  • Check impact before executing

Slippage protection:

  • Set maximum acceptable price change

  • Transaction reverts if exceeded

  • Protects from sandwich attacks

  • Typical: 0.5-1% for normal tokens

MEV (Maximal Extractable Value):

  • Bots can front-run your transaction

  • They see your swap before confirmation

  • Can profit from your trade

  • Use private transactions or limit orders

Failed transactions:

  • Still cost gas even if failed

  • Reasons: insufficient liquidity, slippage, timeout

  • Funds returned but gas lost


Send Functionality

What is sending: Sending (or transferring) is the act of moving tokens from your wallet to another wallet address. It's the most fundamental blockchain operation.

Understanding Token Transfers

The process:

  • From: Your wallet (the sender)

  • To: Recipient's wallet address

  • Amount: Quantity of specific token

  • Irreversible: Cannot undo once confirmed (in real blockchain)

Use cases:

  • Paying for goods/services

  • Sending to friends/family

  • Moving tokens between your own wallets

  • Distributing tokens to team/community

  • Donations/tips

  • Payment for work/services

Critical importance: In production blockchain:

  • Transactions are PERMANENT

  • Wrong address = permanent loss

  • No customer service to reverse

  • Always verify addresses multiple times

  • Start with small test transaction if unsure

How to Send Tokens

  • Valid recipient address

  • Amount > 0 and ≤ balance

  • All fields completed

Send Best Practices

Critical safety measures:

1. Triple-check addresses:

  • Verify first 6 characters

  • Verify last 4 characters

  • Check middle section too

  • Use Contacts feature for frequent recipients

  • Start with small test transaction for new addresses

2. Use Contacts:

  • Save frequently-used addresses

  • Reduces copy-paste errors

  • Quick access

  • Organized management

3. Start small:

  • For new addresses, send small amount first

  • Confirm receipt

  • Then send full amount

  • Costs more but worth the security

4. Save transaction records:

  • Screenshot confirmation

  • Note transaction hash (in real blockchain)

  • Keep Activity history

  • Document for accounting/taxes

5. Verify before confirming:

  • Read modal completely

  • Check every detail

  • Take a moment

  • Don't rush

Real-World Send Considerations

In production blockchain:

Gas fees:

  • Every send costs network fees

  • Varies: $0.50 to $50+ (Ethereum)

  • Failed sends still cost gas

  • Consider gas when sending small amounts

Transaction time:

  • Not instant (unlike simulation)

  • Ethereum: 15 seconds to 5 minutes

  • Bitcoin: 10-60 minutes

  • Depends on gas paid and network congestion

Confirmations:

  • Transactions get "confirmed" in blocks

  • More confirmations = more security

  • Exchanges require 12+ confirmations often

  • Irreversible after ~6 confirmations

Wrong address scenarios:

Similar address:

  • Attackers can generate similar-looking addresses

  • Check entire address, not just beginning/end

  • Use address book/contacts

Wrong network:

  • Sending ETH address on BSC = lost

  • Each network has different addresses

  • Verify network before sending

Contract address:

  • Some addresses are smart contracts

  • May not accept transfers

  • Can result in lost funds

Cross-chain:

  • Sending BTC to ETH address = lost forever

  • Different blockchains = incompatible

  • Always match token to network


Contact Management System

What are contacts: Contacts allow you to save frequently-used wallet addresses with human-readable names. This is essential for preventing address errors and streamlining transfers.

Why contacts matter:

  • Blockchain addresses are complex (0x + 40 hex characters)

  • Human error rate is high when copy-pasting

  • Frequent recipients need quick access

  • Organization improves workflow

  • Reduces anxiety about wrong addresses

Understanding Contact Types

Two categories:

⭐ Favorites:

  • Your most important contacts

  • Priority display at top

  • Marked with yellow star icon

  • Quick access for frequent transfers

  • Example: Family, business partners, main wallets

📋 All Contacts:

  • Complete contact list

  • Less frequently used addresses

  • Can be promoted to Favorites

  • Organized alphabetically

  • Example: Occasional recipients, backup wallets

Adding a New Contact

Step-by-step guide:

1. Access Contacts Section

  • Click orange "Contacts" quick action

  • Or navigate using tabs

  • Interface loads with contact management view

2. Locate "Add New Contact" Form Appears at top of Contacts section:

  • Prominent header: "Add New Contact"

  • Two input fields

  • Add Contact button

3. Enter Contact Name

Name field requirements:

  • Human-readable identifier

  • Use descriptive names

  • Examples:

    • "Alice Johnson"

    • "Bob - Trading Partner"

    • "Main Exchange Wallet"

    • "Emergency Backup"

    • "Mom's Wallet"

Best practices for naming:

  • Be specific (not just "Friend 1")

  • Include relationship or purpose

  • Use consistent naming scheme

  • Consider adding notes in name (in parentheses)

4. Enter Wallet Address

Address field requirements:

  • Full 42-character address

  • Must start with "0x"

  • Hexadecimal characters (0-9, a-f)

  • Example: 0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb

⚠️ Critical address verification:

  • Copy address from reliable source

  • Verify first 6 and last 4 characters

  • Check for typos

  • Test with small transaction first

  • Wrong address = permanent loss (in real DeFi)

Where to get addresses:

  • Recipient sends via secure channel

Contact Best Practices

Security practices:

1. Verify addresses before adding:

  • Test with small transaction first

  • Confirm with recipient via separate channel

  • Check blockchain explorer

  • Cross-reference multiple sources

2. Use descriptive names:

  • Include full name or business name

  • Add context (purpose, relationship)

  • Avoid ambiguous labels

  • Update names as needed

3. Organize with favorites:

  • Keep frequent contacts starred

  • Review and update regularly

  • Remove unused contacts

  • Maintain clean list

4. Backup your contacts:

  • In real wallets, export contact list

  • Keep separate record

  • Document addresses securely

  • Consider encrypted storage

5. Regular audits:

  • Review contact list monthly

  • Remove obsolete entries

  • Verify addresses still valid

  • Update names/notes

Real-World Contact Management

In production wallets:

MetaMask:

  • Has built-in address book

  • Stored locally in browser

  • Not synced across devices

  • Can export/import

Ledger/Hardware wallets:

  • Contacts managed in companion software

  • Some support labels on-device

  • Enhanced security for address verification

  • Requires manual entry often

Exchange wallets:

  • Whitelisting for withdrawal addresses

  • 24h delay for new addresses (security)

  • Mandatory for some jurisdictions

  • Email/2FA confirmation required

ENS (Ethereum Name Service):

  • Use names instead of addresses

  • Example: "alice.eth" instead of "0x742d..."

  • Resolves to current address

  • Decentralized domain system

  • Costs to register

  • Annual renewal fees

Best practice:

  • Maintain contacts in multiple places

  • Use ENS names when possible

  • Keep paper backup of critical addresses

  • Verify addresses through multiple channels


Confirmation Modals

What are confirmation modals: Confirmation modals are pop-up dialogs that appear before executing critical actions. They serve as the final checkpoint to review transaction details and prevent costly mistakes.

Why they exist:

  • Prevent errors: Last chance to catch mistakes

  • Educational: See exactly what will happen

  • Security: Matches real wallet behavior

  • Transparency: No hidden actions

  • Control: Explicit user consent required

Philosophy: In blockchain, transactions are irreversible. Confirmation modals are your last line of defense against:

  • Wrong addresses

  • Incorrect amounts

  • Unintended actions

  • Scam transactions

  • Fat-finger errors

Modal Structure

Standard components across all modals:

Header section:

  • Title: Describes the action (e.g., "Confirm Swap")

  • Close button (X): Cancel and close modal

  • Dark/light theme adaptive

  • Clean, clear typography

Content section:

  • Action details: Specific to transaction type

  • Visual separators: Make information scannable

  • Formatted displays: Easy-to-read layouts

  • All relevant data: Nothing hidden

Alert box:

  • Blue background: Attention-grabbing

  • Alert icon: Visual warning indicator

  • "Confirm Transaction" heading

  • Warning text: "Please review the details carefully"

  • Purpose: Reminds user this is important

Footer section:

  • Cancel button (gray):

    • Left side

    • Aborts transaction

    • Closes modal

    • No changes made

    • Safe option

  • Confirm button (gradient blue-purple):

    • Right side

    • Executes transaction

    • Irreversible (in real blockchain)

    • Prominent styling

    • Requires deliberate click

Swap Confirmation Modal

Specific to token swaps

Title: "Confirm Swap"

Content displays:

"You Pay" section:

  • Label in gray

  • Amount + token symbol

  • Large font size (2xl)

  • Bold weight

  • Example: "10.0000 ETH"

  • Gray background box

  • Rounded corners

Visual separator:

  • Centered arrow icon (→)

  • Circular background

  • Indicates transaction direction

  • Purple accent color

  • Clear flow visualization

"You Receive (estimated)" section:

  • Label in gray

  • Calculated amount + token symbol

  • Large font size (2xl)

  • Bold weight

  • Example: "28,470.0000 USDT"

  • Gray background box

  • Note: "(estimated)" emphasizes approximation

Why "estimated":

  • Prices can change between submission and confirmation

  • Blockchain confirmation takes time

  • Slippage may occur

  • Final amount may vary slightly

  • Real DEXs work the same way

What to verify:

  1. FROM token is correct

  2. FROM amount is intended

  3. TO token is correct

  4. TO amount is reasonable (check rate)

  5. You can afford the FROM amount

Common mistakes to catch:

  • Wrong token selected

  • Decimal point error (10 vs 1.0)

  • Swapping in wrong direction

  • Unreasonable exchange rate

Send Confirmation Modal

Specific to token transfers

Title: "Confirm Send"

Content displays:

"Amount" section:

  • Label in gray

  • Quantity + token symbol

  • Large font (2xl)

  • Bold weight

  • Example: "100.0000 USDT"

  • Gray background box

"Recipient" section:

  • Label in gray

  • FULL address displayed (not truncated)

  • Example: 0x742d35Cc6634C0532925a3b844Bc9e7595f0bEb

  • Monospace font for clarity

  • Break-all for long addresses

  • Gray background box

⚠️ CRITICAL VERIFICATION: This is your LAST CHANCE to verify the recipient address:

  • Check first 6-8 characters

  • Check last 4-6 characters

  • Verify middle section too

  • Compare against source

  • One wrong character = lost forever

What to verify:

  1. Amount is correct

  2. Token is correct

  3. Address is EXACT (character by character)

  4. You can afford to send

  5. Recipient confirmed this is their address

Red flags:

  • Address looks unfamiliar

  • Amount seems wrong

  • Different token than intended

  • Recipient never confirmed address

Faucet Confirmation Modal

Specific to faucet requests

Title: "Confirm Faucet Request"

Content displays:

"You will receive" section:

  • Label in gray

  • Amount + token symbol

  • Large font (2xl)

  • Bold weight

  • Example: "50.0000 ETH"

  • Gray background box

Simpler than other modals:

  • Only receiving, not sending

  • No risk of loss

  • Educational context

  • Lower stakes

What to verify:

  1. Token is correct

  2. Amount is as intended

  3. This is what you want to test with

Why confirm faucet requests:

  • Maintains consistent UX

  • Teaches confirmation habit

  • Prevents accidental clicks

  • Builds muscle memory for real DeFi

Modal Interaction Patterns

  • Take your time - no rush

Closing without action:

  • Click X button (top right)

  • Click Cancel button (bottom left)

  • Click backdrop outside modal

  • Press Escape key (future enhancement)

  • No changes made

  • Safe to close anytime

Confirming:

  • Click Confirm button (bottom right)

  • Action executes immediately

  • Modal closes

  • Toast notification appears

  • Changes take effect

  • (In real blockchain) Transaction submitted to network

Best Practices for Confirmation Modals

Always: ✅ Read every field ✅ Verify amounts ✅ Check addresses character-by-character ✅ Take your time ✅ When in doubt, cancel and re-check

Never: ❌ Rush through confirmations ❌ Assume details are correct ❌ Ignore the alert box ❌ Confirm without reading ❌ Let someone pressure you to confirm quickly

Mental checklist:

  1. Is this the action I intended?

  2. Are all values correct?

  3. Is the recipient address verified?

  4. Can I afford this?

  5. Am I certain about this?

If answer to ANY is "No" or "Maybe" → Click Cancel

Real-World Modal Importance

In production DeFi:

MetaMask confirmations:

  • Shows gas fee estimate

  • Displays contract interaction details

  • Can view transaction data (advanced)

  • Signing requires password/biometric

  • Ledger requires physical button press

Critical differences from simulation:

  • Gas fees: Cost money even if failed

  • Irreversible: No undo button exists

  • Scams: Malicious sites can trigger fake modals

  • Timing: Price can change during confirmation

  • MEV: Bots may front-run your transaction

Common scams to watch for:

  • Unlimited approval modals: Granting unlimited token access

  • Fake token swaps: Scam tokens that look legitimate

  • Drainer contracts: Empty your wallet when approved

  • Phishing sites: Identical-looking fake sites

Protection strategies:

  • Use hardware wallets for large amounts

  • Always verify contract addresses

  • Check transaction details in block explorer

  • Start with small test transactions

  • Use reputable interfaces only

  • Keep wallet software updated
